SPRING BE D-BOTTOM.

Application filed May 18, 1907.

To all whom it may concern:

Be it known that I, JosnPn G. VENABLE, Sn, a citizen of the UnitedStates, residing at Mahomet, in the county of Champaign and State ofIllinois, have invented new and useful Improvements in SpringBed-Bottoms, of which the following is a specification.

This invention relates to spring bed bottoms of that type provided withtop and bottom longitudinal and cross members with resilient elements orcircular springs disposed between them.

The invention has for one of its objects to improve and simplify theconstruction and operation of devices of this character so as to becomparatively easy and inexpensive to manufacture, of durable design,and composed of few parts.

A further object of the invention is the provision of stop devices orbumpers for limiting the compression of the circular springs so as toprevent breakage thereof under excessive Weight.

A still further object is the provision of a simple and effective meansfor securing the longitudinal and cross members and spring elementstogether and at the same time securing the bumpers in position.

With these objects in view and others, as will appear as the descriptionproceeds, the invention comprises the various novel fea tures ofconstruction and arrangement of parts which will be more fully describedhereinafter and set forth with particularity in the claims appendedhereto.

In the accompanying drawings, which illustrate certain of theembodiments of the in vention, Figure 1 is a plan view of one portion ofa bed bottom. Fig. 2 is a vertical section on line 22, Fig. 1, drawn onan enlarged scale. Fig. 3 is a perspective view of one of the circularsprings with the bumpers applied thereto. Fig. 4 is a detail sectionalview on line 44, Fig. 2. Fig. 5 is a fragmentary plan View of a modifiedform of bed bottom. Fig. 6 is a longitudinal section thereof. Fig. 7 isa perspective view of one of the circular springs and adjacentparts.Fig. Sis a vertical section on line 88, Fig. 6, drawn on an enlargedscale. Fig. 9 is a plan view of one of the blanks from which the stopsor bumpers are made.

Similar reference characters are employed to designate correspondingparts throughout the several views.

Referring to Figs. 1 to 4, the body of the Specification of LettersPatent.

bed bottom comprises a metallic framework composed of top and bottomlongitudinal and transverse members 1 and 2 which, in the )resentinstance, are made of spring wire stool; of suitable gage. Thecorresponding top and bottom longitudinal members 1 are preferably asingle length of wire and are connected at their ends by thesemi-circular bends 3, while the cross members 2 are arranged in pairsand each pair is connected by a horizontal connection portion 4, asshown in Fig. 1. Between the top and bottom members are disposedcircular springs 5 arranged at the points of crossing of the members.These rings are provided with openings 6 at diametrically oppositepoints for receiving tie wires 6, whereby the parts can be boundtogether. The cross members 2 are preferably disposed between thecorresponding members 1 and extend through the springs 5. Arrangedwithin each spring are oppositely disposed bumpers or stops 7 that limitthe compression of the springs so that breakage of the latter iseffectively prevented. Each device 7 comprises a strip of metal bentinto rectangular form with overlapping ends, which latter are perforatedas indicated at 9 in Fig. 9, for the purpose of receiving the tie wires.

As shown in the right lower corner of Fig. 2, the tie wires are ofU-shaped form and are straddled over cross members 2, and through theapertures 9 of the device 7 and openings 6 of the springs, and thencrossed once over the members 1, as indicated at 10, Fig. 3, so thattheir extremities can be brought downwardly on opposite sides of thesprings and coiled around and anchored on the members 2, as indicated at11. By this means, the members constituting the body of the bed bottomand springs and bumpers are secured together by a single device, and insuch manner that the bed bottom can be quickly and readily constructedor repaired when occasion requires.

In the modification shown in Figs. 5 to S, inclusive, the longitudinaland transverse members 1 and 2 are constructed of strip metal instead ofbeing round in cross section, as shown in Fig. 1. The longitudinalmembers 1 are provided with apertures 12 for receiving the tie wires 13,and these wires are straddled over the members 2 and through theapertures 9 of the bumpers 7, and openings 12 of the longitudinalmembers, as shown at the right of Fig. 6. The ends of the tie wire arethen bent transversely over the longitudinal member 1, as indicated inFig. 8, and thence downwardly along the sides of the longitudinalmember, spring 5 and bumper 7, so as to be coiled at 14 around the crossmember 2.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the apparatuswhich I now consider to be the best embodiment thereof, I desire to haveit understood that the apparatus shown is merely illustrative and thatsuch changes may be made when desired, as are within the scope of theclaims.

Having thus described the invention, what I claim is 1. A spring bedbottom comprising top and bottom longitudinal and transverse crossmembers, circular springs disposed between them and having diametricallydisposed apertures, stop devices or bumpers arranged within each springfor limiting the compression thereof and consisting of metal stripshaving apertured ends overlapping and disposed against the members, andtie wires extending. through the apertures of the springs and devicesand arranged to bind the devices to the said members.

2. A spring bed bottom comprising top and bottom longitudinal andtransverse members, circular springs having diametrically disposedopenings, bumpers arranged at the openings and within the springs andhaving portions disposed between the members where they cross, and tiewires for binding the members together at the points where they cross,and passing through the apertures of the springs for securing the latterand bumpers to the members and preventing lateral movement of thebumpers.

3. In a spring bed bottom, the combination of a resilient element, crossmembers disposed one within and one without the element, a bumperconsisting of a strip of metal having its ends disposed between theinternal member and element, and a tie wire for securing all of saidparts together.

4. In a spring bed bottom, the combination of an annular resilientelement having an aperture, cross members one extending within and theother without the element at the aperture thereof, a strip of metalforming a bumper having apertured ends overlapping and disposed betweenthe internal member and element at the aperture thereof, a tie wirestraddling the internal member and passing through the apertures of thebumper and element and passing over the outer member and having its endsfastened to the inner member.

5. A spring bed bottom comprising top and bottom longitudinal andtransverse members, endless springs disposed between the top and bottommembers, a pair of hollow oppositely disposed bumpers arranged withineach spring, and a fastening Wire se curing each bumper in fixedrelation to the adjacent ring and also securing it to both members andholding the members together.

6. In a spring bed bottom, the combination of an endless resilientelement having apertures at diametrically opposite points, crossedmembers arranged at diametrically opposite points and adjacent theapertures, hollow bumpers disposed within the element and through eachof which a member eX- tends, and a binding wire securing the bump ersand elements together and also to the cross members.

In testimony whereof, I afliX my signature in presence of two witnesses.
